Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a life-threatening condition that causes renal failure. Multiple myeloma (MM) is a malignant proliferation of monoclonal plasma cells in the blood that can also cause renal failure. The two diseases have high morbidity and mortality rates in the elderly, with a poor prognosis. A 64-year-old female presented to Xinqiao Hospital (Chonqing, China) with fatigue and a poor appetite that had been apparent for 6 weeks. Laboratory tests revealed a serum creatinine level of 10.31 mg/dl, a cytoplasmic ANCA titer of 1:10, a positive result for myeloperoxidase and a serum globulin level of 3.96 g/dl. A renal biopsy revealed crescent glomerulonephritis, combined with the rapid progression of renal function. Based on these observations (ANCA titer, crescent glomerulonephritis and rapid progression of renal function) a diagnosis of AAV was established. MM was confirmed by serum immunofixation electrophoresis combined with bone marrow aspiration. The present study discusses what is, to the best of our knowledge, the first case of AAV coexisting with MM in order to highlight it as a clinical concern.

Granulomatosis with polyangiitis (GPA, previously known as Wegener's granulomatosis) is an autoimmune systemic small-vessel vasculitis, associated with the presence of anti-neurophil cytoplasmic antibodies with a cytoplasmic staining pattern (c-ANCA). It is characterized by necrotizing granulomas, usually affecting the airways and kidneys. GPA should be considered when patients do not improve despite adequate treatment of otologic symptoms, when patients have unspecific symptoms suggesting systemic disease (e.g. fever, malaise), or when other organs are involved (kidney, lungs, etc.). We present an interesting case of a 14-year-old female with eight-weeks of bilateral otalgia, unilateral facial nerve palsy, decreased appetite, and fatigue refractory to steroid, anti-viral, and antibiotic treatment ultimately diagnosed with GPA.

Pneumoperitoneum, the presence of free air within the peritoneal cavity, is often caused by the perforation of gas-containing viscus and commonly requires surgical treatment. However, in patients with peritoneal dialysis, free air is commonly seen on X-ray. We present the case of a patient with peritoneal dialysis with marked pneumoperitoneum. A 75-year-old Japanese male with end-stage renal disease due to antineutrophil cytoplasmic antigen-associated vasculitis had been receiving continuous ambulatory peritoneal dialysis for 9 years. He had a poor appetite and general malaise without abdominal pain or fever. These symptoms gradually worsened, and he was hospitalized. At the time of admission, chest X-ray revealed bilateral free air in the abdomen. Subsequent computed tomography of the abdomen revealed marked pneumoperitoneum. Peritonitis due to perforation of the digestive tract was considered; however, the absence of abdominal pain, fever, and turbidity of dialysis drainage indicated that peritonitis was unlikely. Insufficient air venting during continuous ambulatory peritoneal dialysis bag replacement was suspected. The bag was carefully changed, resulting in a gradual decrease in the free air. We encountered a patient with continuous ambulatory peritoneal dialysis who had significant free air in the abdominal cavity in the absence of peritonitis. The source of the air was determined to be the dialysis bag due to insufficient venting during replacement. This case underscores the importance of instructing patients with continuous ambulatory peritoneal dialysis on the thorough removal of air from the bag during replacement.
